So, after three blog posts, what is the moral of this Blue Ridge Numerics’ “CFD Comparison Chart” saga?
Well, clearly one should not believe every “CFD Comparison Chart”! – or even the many “charts” that one vendor has put out. Rather, the story suggests that people who are thinking of buying a CFD tool for the first time might be well advised to be wary of what vendors claim about their own software … Read More

In my earlier posts I pointed out some glaring errors in the “CFD Comparison Chart” that Blue Ridge Numerics released on March 19th this year. Once we became aware of the “Chart” we quickly wrote a letter to Ed Williams, the CEO of Blue Ridge Numerics, and asked that they reveal the technical workings behind their outrageous claims. Including those I’ve mentioned, we pointed out a total of 6 very obvious … Read More

In my last post I pointed out a very obvious mistake in Blue Ridge Numerics’ “CFD Comparison Chart” of March 19th this year, which incorrectly stated that FloEFD can only handle incompressible sub-sonic flows.
The reason I highlighted this as the most obvious mistake in the “CFD Comparison Chart” is that FloEFD can trace its history back to the Russian Aerospace Industry in the late 1980s originating … Read More

Rarely do I get a feeling of déjà vu in my professional life, but in March of this year something I was shown gave me a flashback to the 1980s. Some people will remember those halcyon days of two decades ago when commercial CFD was still in its infancy. Way back then the big commercial CFD vendors (Fluent, CHAM, Fidap, Flomerics, STAR-CD, and AEA) would regularly bring out CFD Comparison Charts comparing … Read More

If you’re involved in CFD in education in any way this will be of interest to you. Since shortly after Flomerics were acquired by Mentor Graphics we’ve been working towards getting out products into Mentor’s Higher Education Program (HEP), and we’ve finally got it done.
To my knowledge, the availability of potentially millions of dollars worth of commercial CFD software, plus support and training, … Read More

Last time I promised I’d drill down into more detail about the difference between the CAD-integrated up-front approach to CFD and CAD-embedded Concurrent CFD. CAD-integrated CFD tools are essentially stand-alone tools launched from within the CAD system whereas Concurrent CFD is fully built into the CAD system. So what’s the real difference between the two?
CAD-integrated CFD tools use the same approach … Read More

Back in June I posted ‘Air – Is it Running Out of Gas?’ and put forward the view that for general computing applications air isn’t running out of gas just yet. There are a couple of reasons for that.
One is that I suspect the general public has concerns about leaks. Most people have passed cars stuck on the highway with a blown heater hose and seen water on the ground, and I’ve had an automotive water … Read More

I was on a conference call and WebEx yesterday with the NAFEMS CFD Working Group, of which Mentor Graphics is a member. One of the people on the call had a lot of background noise on his phone, which turned out to be a due to a fan by his desk to keep his computer cool.
Computational Fluid Dynamics (CFD) is a memory hungry, CPU intensive activity so I guess he was running a fairly substantial case. … Read More

Some people think that because Concurrent CFD is so easy to use it must be simplistic. Nothing could be further from the truth. FloEFD has some very sophisticated physical models for cavitation, combustion, etc. plus by being CAD-embedded it’s also easy to use the CFD results to drive other simulation packages within the MCAD environment. Not limited to upfront design, Concurrent CFD can be used continuously … Read More

Using CAD-embedded CFD upfront and throughout the design process is the only way to go when it comes to compressing design schedules. We call this approach Concurrent CFD, as the CFD analysis can be done concurrently with design changes, taking upfront CFD to the next level. The product’s performance can be checked at each design iteration, leading to a more fluent CFD process that gives increased confidence … Read More
